I think this is coming from the before traversal hook of the session 
data manager.  What you can do is
create a session_data_manager in the old spot (the root) and then change 
its SESSION attribute name from the management screens to blank (null) 
-- that will get rid of the traversal hook -- then you can delete it and 
replace it with a dummy object again.
